Hi,

I have a X61s, now about 2 years old. Used it a lot, carried it around
nearly every second day. Never had any problems with the battery.

Now I get:

[arno@tiger]$ cat /proc/acpi/battery/BAT0/info
present:                 yes
design capacity:         74880 mWh      =E2=87=90
last full capacity:      52420 mWh      =E2=87=90
battery technology:      rechargeable
design voltage:          14400 mV
design capacity warning: 2621 mWh
design capacity low:     200 mWh
capacity granularity 1:  1 mWh
capacity granularity 2:  1 mWh
model number:            93P5030
serial number:            6195
battery type:            LION
OEM info:                SONY

Ok, maybe the battery is bad now and will hold only 52Wh. But actually,
it does not:

[arno@tiger]$ cat /proc/acpi/battery/BAT0/state
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mW
remaining capacity:      1800 mWh       =E2=87=90
present voltage:         16195 mV

The machine is plugged in, but the remaining capacity stays at 1800 mWh.
This happened just a few days ago, since then the remaining capacity
changed from like 1650 mWh to 1800 mWh.

So my question: what can I do? Is the battery useless? Can I recover it
anyhow? Could this be a software issue or is it hardware?

cheers
Arno
